   Areas affected...parts of southern South Carolina and adjacent
   eastern Georgia

   Concerning...Tornado Watch 679...

   Valid 102248Z - 110045Z

   The severe weather threat for Tornado Watch 679 continues.

   SUMMARY...Environmental conditions are becoming less conducive to
   thunderstorms capable of producing tornadoes.  Parts of the
   remaining valid portion of Tornado Watch 679 could be locally
   extended an hour or so in time this evening, but a new tornado watch
   is not anticipated.

   DISCUSSION...Cool surface ridging is maintaining a considerable
   influence across much of the southern Mid Atlantic, as far south and
   west as portions of the northeastern South Carolina coastal plain
   into the Piedmont, where near surface lapse rates remain isothermal
   or more stable.  Strongest low-level shear is focused within the
   cooler air, and forecast to become increasingly modest within the
   moist sector through this evening.  Coupled with at least subtle
   boundary-layer cooling within the moist sector over the next couple
   of hours,  the risk for convection capable of producing tornadoes
   seems likely to diminish by or not long after 11/00Z, even as
   upstream mid-level troughing slowly pivots east-northeast of the
   lower Mississippi Valley.
